SPECIFICATION forming part of Letters Patent No. 632,317, datedSeptember 5, 1899.-

Application filed October 7, 1897- Serial No. 654,487. (No model.)

To aZZ whom it may concern:

Be it known that we, CHARLES EDWARD MIDDLETON, FRANCIS PHILIP MIDDLETON,and ARTHUR THOMAS MIDDLETON, subjects of the Queen of the United Kingdomof Great Britain and Ireland, residing at Adlington, in the county ofLancaster, England, have invented certain new and useful Improvements inDyeing Apparatus; and we do hereby declare that the following is a full,clear, and exact description thereof.

Our invention consists in certain improvements in what is known asObermiers apparatus, used for dyeing cops under hydraulic pressure, andrelates more particularly to the boxes or cases employed forholding thecops during the process. The cases as at present used are open at theends as well as the sides and are difficult to pack with cops in such amanner as to insure a perfect process of dyeing, a great quantity ofwaste material having to be used to fill the ends of the cases and theinterstices between the cops and also between the case and thecompartment it is in. In addition to this the pressure necessary inattempting to obtain a perfect fit of the cases, &c., in the vatseriously damages the cops.

To overcome these difficulties is the object of our invention. This weaccomplish as fol lows: We form the cop-cases with closed ends andsides, (which may be perforated,) leaving only two sides open, and uponthe edges of the open sides we form or fit frames or surfaces ofsuitable metal, planed or otherwise formed to a true surface, which fitor slide into suitable frames or slides in the vat or chest, so as toobtain a perfect fit or joint between the open sides of the case and thevat, this being further facilitated by means of a thin strip ofindia-rubber or other suitable material attached to one or both of thesurfaces in contact. The cops are placed sidewise into the case, verylittle waste packing being required, and the two movable perforatedplates at the sides are slid into position in suitable grooves in theflanges or surfaces before mentioned. lVe also furnish the compartmentof the vat or chest, in which the cop-case is placed, with a suitablemetal lid with similar planed (or other) contact-surfaces andindia-rubber (or other) joint, so as to insure a tight joint without anyloose or waste packing. By this arrangement the 11ydraulic pressure isutilized to tighten the joint of the outside of the case against theouter side of the vat or chest, making it impossible for any liquor topass out of the vat or chest except through the cop-case and cops.

Referring to the drawings sent herewith, Figures 1, 2, and 3 arerespectively a front, side, and top View of our improved cop-case. Figs.4: and 5 are respectively a cross-section and plan of the vat or chestwith our improved fittings.

The cop-case a is fitted with flanges or surfaces b, planed to a truesurface, as before mentioned, and completely closed, excepting on-twosides 0 c, which are fitted with perforated and movable plates (1, whichslide in grooves b in flanges 1). One of these perforated plates (1 isshown only partly closed in Figs. 1 and 2. The cop-case a is reversibleand is fitted with a suitable handle c at each end for convenienthandling. The cop-case to is placed upright in compartment f of vat orchest g, being guided into position by slide or guide h, which issometimes furnished with a suitable spring h to press the faces orflanges 19 of the cop-case a firmly against corresponding faces '1: onthe outlet side of the compartment f. A suitable metal lid is is thenfitted upon the top of compartment f, fitting upon faces or flanges Zand screwed up tight by means of screw on and handle n. All otheroutlets being now tightly closed, the dye-liquor is pumped in by inlet 0and passes out through cop-case a (pressing it firmly against the sideof the compartment f and so stopping all leakage) in the direction shownby arrows on drawings.

Having now particularly described our invention, what we claim, anddesire to secure by Letters Patentof the United States, is
